Embodiment 1

[0019] Embodiment 1: Yeast waste water produces bacillus licheniformis bio-organic fertilizer

[0020] Yeast wastewater pretreatment: adjust the pH of the wastewater to about 7.5 with plant ash rich in potassium carbonate from a biomass thermal power plant, and sterilize at 115°C for 15 minutes.

[0021] Preparation of liquid seeds: Preparation of liquid seeds: inoculate Bacillus licheniformis preserved on a slant into a triangular flask containing pretreated yeast wastewater, and vibrate at 35° C. for 24 hours at 150 rpm to obtain liquid seeds.

[0022] Liquid fermentation: Inoculate liquid seeds with a volume ratio of 5% in a fermenter equipped with pretreated yeast wastewater, and culture at 35°C with sterile air for 20 hours; the cultured fermentation broth is counted by plate bacteria, and the number of viable bacteria up to 9×10 8 CFU / ml or more, the obtained fermentation broth can be used after dilution as a liquid bacterial agent.

[0023] Preparation of bio-organic ...

Embodiment 2

[0024] Embodiment 2: Bacillus licheniformis bio-organic fertilizer is used to prevent cucumber damping-off

[0025]Cucumber damping-off is a disease caused by fungal infection. The soil in the greenhouse where cucumbers have been planted for many years is collected, and inoculated with Pythium melon fruit ( Pythium aphanidermatum ), mix them evenly, put them into flowerpots, set up 2 groups of flowerpots, 10 pots in each group, and keep higher humidity and lower light intensity in the greenhouse at 15°C to 20°C. The first group of flower pots were directly sown with cucumber seeds, 15 seeds per pot, as a control. Before sowing cucumber seeds, group 2 mixed 0.3% Bacillus licheniformis biocontrol agent into the soil by weight, and then sowed 15 seeds per pot. The total number of seedlings was counted after unearthed, and the total number of lodging seedlings was counted after the seedlings grew 1 true leaf and before 2 true leaves. The results showed that the lodging rate of...

Embodiment 3

[0026] Embodiment 3: Bacillus licheniformis bio-organic fertilizer is used to increase the output of vegetables and improve the quality of vegetables

[0027] Using the vegetable greenhouse plot experiment, set up 8 experimental plots with exactly the same conditions, each plot 60m 2 , 2 plots are a group of parallel experiments, divided into 4 groups, planting small rapeseed, in the seedling stage of small rapeseed, the 2 plots of the first group were not fertilized as a control; the 2 plots of the second group were each applied with 1×10 7 100 kg of CFU / gram of Bacillus licheniformis bio-organic fertilizer was used as the base fertilizer, and 1×10 7 The dilution of the Bacillus licheniformis fermentation liquid of CFU / ml; The 2 plots of the 3rd group apply urea once respectively after the rape germinates completely and after 3 weeks according to the fertilization rate of 15 kg / mu; The amount of fertilization per mu was applied urea once after the rape fully germinated and t...

Abstract

The invention relates to a method for producing multifunctional bio-organic fertilizer through resource utilization of yeast wastewater, and belongs to the technical fields of resource utilization of high-concentration wastewater and bio-organic fertilizer. The bacterial strain adopted in the present invention is a high-efficiency plant growth-promoting bacterium isolated and screened from soil—Bacillus licheniformis ( Bacillus licheniformis ) B4 strain, which is preserved in the General Microbiology Center of China Committee for the Collection of Microbial Cultures, and the preservation number is: CGMCC No. 6677. The present invention uses yeast wastewater as a fermentation medium to cultivate Bacillus licheniformis on a large scale to prepare bio-organic fertilizer capable of preventing and controlling plant diseases and promoting plant growth. The process has low production cost and simple operation, and can also make resource utilization of yeast wastewater, Reduce pollution emissions. The bio-organic fertilizer produced by the invention is used in the production of vegetables, not only can increase the yield, but also can improve the quality of tea gardens and vegetables, showing broad application prospects.

Description

technical field [0001] The invention relates to a method for producing multifunctional bio-organic fertilizer by resource utilization of yeast wastewater. The bio-organic fertilizer has the functions of antagonizing plant diseases, promoting plant growth and improving crop quality, and belongs to high-concentration wastewater resource utilization and bio-organic fertilizer technology field. Background technique [0002] Yeast is a single-celled eukaryotic microorganism, which is the earliest microorganism used in the history of human civilization. At present, yeast is widely used in food, brewing, medicine, cosmetics, feed and other industries. In recent years, with the rapid development of my country's pharmaceutical industry and food industry, the yeast industry has also developed rapidly, and the domestic production of active dry yeast has exceeded 200,000 tons per year. my country's existing large-scale yeast production companies mainly include Angel, Marley, Danbaoli,...
